Product details
Overview
SBR20100CT-G from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier with 100V peak repetitive reverse voltage, 0.82V max forward voltage at 10A/25°C, and 0.1mA max reverse leakage at 100V/25°C. It uses patented SBR® technology for superior avalanche ruggedness versus Schottky diodes and is optimized for high-efficiency DC-DC converters and AC-DC adapters operating under thermally demanding conditions.
For engineers reviewing the SBR20100CT-G datasheet, SBR20100CT-G pinout, SBR20100CT-G application, or SBR20100CT-G equivalent, key selection criteria include its low VF stability across temperature, 150A non-repetitive surge rating, TO220AB package thermal resistance (2°C/W junction-to-case), and validated performance as a freewheeling diode in synchronous rectification topologies.
Technical Context
This dual-diode rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling symmetrical current handling in center-tapped transformer or dual-phase output configurations. Its SBR® structure delivers avalanche energy rating of 10mJ and peak avalanche power of 2.9kW at 10µs, exceeding standard Schottky limitations without requiring external snubbers.
The device operates across –65°C to +175°C junction temperature range with reverse leakage tightly controlled at ≤10mA at 125°C - critical for maintaining reliability in high-temperature industrial power supplies. Thermal resistance of 2°C/W (TO220AB, with 50×50×23mm heatsink) supports continuous 20A total conduction when properly heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage per leg; defines safe operation in 48V–72V bus systems with margin. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; enables 20A total dual-leg output capability. |
| VF (max) | 0.82 V @ 10A/25°C - Low conduction loss improves efficiency >95% in 12V-output DC-DC stages. |
| IR (max) | 0.1 mA @ 100V/25°C - Ultra-low leakage prevents thermal runaway in high-temp ambient environments. |
| EAS | 10 mJ - Avalanche energy rating ensures robustness against inductive switching transients without failure. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO220AB) allows direct heatsink mounting for high-power density designs. |
| IFSM | 150 A - Non-repetitive surge rating supports reliable cold-start and fault-current handling in SMPS. |
Pinout & Package
Package: TO220AB - Molded plastic case, UL 94V-0 rated, matte tin-plated copper leadframe, 1.85g weight. Designed for through-hole mounting with integrated heatsink tab (cathode-connected tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode for first diode leg | Connects to primary-side switch node or transformer winding end; carries up to 10A continuous. |
| Pin 2 (Cathode) | Common cathode terminal | Internally bonded to metal tab; serves as main output node and thermal path to heatsink. |
| Pin 3 (Anode 2) | Input anode for second diode leg | Used for dual-phase or center-tapped secondary rectification; electrically isolated from Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Enables 10mJ avalanche energy rating - 3× higher than comparable Schottky diodes - eliminating need for external clamping in flyback converters. |
| Low VF drift over temperature | 0.75V max at 10A/125°C - maintains <5% efficiency drop from 25°C to 125°C, reducing thermal design margin requirements. |
| Green packaging | Lead-free, halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) compliant with RoHS 2 and JEDEC J-STD-020. |
| High-temperature IR stability | ≤10mA leakage at 100V/125°C - prevents thermal runaway in enclosed power modules operating at 105°C ambient. |
Applications
| Server VRM Output Stage | Industrial AC-DC Adapter |
|---|---|
Use Scenario: High-current, low-voltage output rectification in 48V-input server voltage regulator modules with dual-phase interleaved topology. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing discrete Schottky pairs to reduce conduction loss and footprint. Use Value: 0.82V VF at 10A lowers power dissipation by 1.8W per leg vs. typical 0.95V Schottky, enabling 5% higher full-load efficiency. |
Use Scenario: Secondary-side rectification in universal-input (90–264VAC) 24V/10A industrial power adapters with forced-air cooling. IC Role / Device Role / Timing Role: Freewheeling diode in quasi-resonant flyback converter, handling 150A surge during startup. Use Value: 10mJ avalanche rating withstands reflected voltage spikes without derating, eliminating snubber components and saving PCB area. |
| Telecom DC-DC Brick | Automotive Infotainment Power Supply |
Use Scenario: Input rectification stage in 36–75VDC telecom brick converters delivering ±12V outputs for base station control cards. IC Role / Device Role / Timing Role: Blocking diode preventing backfeed between redundant input rails while supporting hot-swap sequencing. Use Value: 0.1mA IR at 25°C ensures <100µW standby loss per leg - critical for meeting ETSI EN 300 386 Class C idle-power limits. |
Use Scenario: 12V-to-5V/3.3V buck converter input rectification in automotive infotainment head units exposed to under-hood ambient up to 105°C. IC Role / Device Role / Timing Role: Input protection diode isolating downstream DC-DC from battery reverse-polarity and load-dump transients. Use Value: Stable 10mA IR at 125°C prevents thermal runaway during prolonged high-ambient operation, extending MTBF beyond 100,000 hours. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH06-M3 | 60V VRRM, 20A total, VF = 0.62V @ 10A/25°C, RθJC = 2.5°C/W (TO220AC) | Limited to ≤48V systems; lower VF improves light-load efficiency but insufficient for 100V bus designs. | Select only if system VRRM requirement is ≤60V and lowest possible VF is prioritized over surge robustness. |
| ON Semiconductor MUR20100CT | 100V VRRM, 20A total, VF = 0.92V @ 10A/25°C, EAS = 5.5mJ, RθJC = 2.2°C/W (TO220AB) | Higher VF increases conduction loss; lower avalanche rating requires external TVS for same transient immunity. | Choose when cost sensitivity outweighs efficiency and ruggedness needs - acceptable for non-critical consumer adapters. |
Compared with VS-20CPH06-M3 and MUR20100CT, SBR20100CT-G uniquely balances 100V blocking, ultra-low VF, and industry-leading 10mJ avalanche capability - making it optimal for high-reliability, high-efficiency industrial and telecom power where thermal margin and transient immunity are non-negotiable.

FAQ
Is SBR20100CT-G pin-compatible with standard TO220AB dual-diode rectifiers?
Yes - SBR20100CT-G uses the industry-standard TO220AB outline with identical mechanical dimensions, hole spacing, and terminal layout as conventional dual-diode rectifiers like MUR20100CT. Pin 1 and Pin 3 are isolated anodes; Pin 2 is the common cathode tab, which is internally connected to the metal mounting surface.
What is the maximum continuous case temperature for reliable operation?
The device supports continuous operation up to +175°C junction temperature. With RθJC = 2°C/W and a typical heatsink interface resistance of 0.5°C/W, sustained case temperatures up to +125°C are achievable at 20A total current - verified per Figure 4 derating curve in DS30956 Rev. 16-2.
Does the "-G" suffix indicate full RoHS compliance including halogen-free status?
Yes - the "-G" suffix denotes Diodes Incorporated's Green packaging: lead-free per RoHS 2 (2011/65/EU), halogen-free (<900ppm Br, <900ppm Cl, <1000ppm Sb), and antimony-free. This is confirmed in Notes 1–3 of DS30956 and aligns with JEDEC J-STD-020 moisture sensitivity level 1.
Can SBR20100CT-G replace Schottky diodes in existing designs without layout changes?
Yes - it fits the same TO220AB footprint and offers lower VF than most 100V Schottkys (e.g., STPS20H100CG). However, verify that the common-cathode configuration matches your circuit topology; unlike single-diode Schottkys, it cannot be used as an isolated anode-cathode pair without reworking the PCB net connections.
